+#                 LUFA Doxygen Buildsystem Makefile Module.
+# -----------------------------------------------------------------------------
+# DESCRIPTION:
+#   Provides a set of targets to automatically build Doxygen documentation for
+#   a project (see www.doxygen.org).
+# -----------------------------------------------------------------------------
+# TARGETS:
+#
+#    doxygen                   - Build Doxygen Documentation
+#
+# MANDATORY PARAMETERS:
+#
+#    LUFA_PATH                 - Path to the LUFA library core
+#
+# OPTIONAL PARAMETERS:
+#
+#    DOXYGEN_CONF              - Doxygen configuration filename
+#    DOXYGEN_FAIL_ON_WARNING   - Set to Y to fail the build on Doxygen warnings,
+#                                N to continue even if warnings occur
+#    DOXYGEN_OVERRIDE_PARAMS   - Parameters to override in the doxygen
+#                                configuration file
+# PROVIDED VARIABLES:
